Heh.  :)  Was that an intentional mis-parse for fun?  :)

"(ideally I'd prefer [...] FAST solid-state media, say SSDs) ; but
([slow devices such as] flash cards and anything USB need not apply)."

I already run my nightly incremental backups and weekly differentials,
all of which are small, to a ZFS volume on the X4540 which is my NAS.
But if I start putting [currently] 1.6TB monthly full backups there,
that's going to eat up a lot of space fast.  AND I want my full backups
isolated offline and airgapped when not in use.

But it's occurred to me that this doesn't actually HAVE to integrate
*directly* with my backup system.  I can just do what I'm doing now -
run FULL backups to the NAS - and then move the disk volume files off to
a hot-swap SATA or SAS drive.  And maybe keep a copy of only the most
recent FULL online as well.

And looking at it this way, the problem is actually a *lot* simpler than
I'd been thinking it was.  I might even be able to find a rackmount
housing that I can attack directly to asgard (the Thor) and not have the
volume copies go over the wire.  I should even be able to have Bacula
automatically do the copies for me as a post-run job.
